Title: Ramie harvesting and decorticating machine
IPC: D01B1/14
Filed: 1945-02-05
Abstract: 591,720. Harvesting-machines. BRERETON, G. Feb. 5, 1945, No. 2820. [Class 6 (iii)] [Also in Group IX] A ramie harvesting and decorticating machine comprises a wheeled box 1, a table 12 carried by said box externally thereof cutting means 4 ; endless conveyors ; a reel 17 ; a stationary rigid crusher member 30 ; a plurality of spaced rotary scrapers 25, 26 ; a plurality of rollers 34, 35 ; endless conveyors 19, 22 ; a beater 37, and means for emitting cleaned stalks from said box. In operation, the machine is drawn over the ground and the stalks cut by knives 4 are deposited on an endless conveyor by means of a reel 17. The inclined portion of the conveyor co-acts with a parallel conveyor to carry the cut stalks to the table 12 from where they are fed by hand to the downwardly inclined conveyor 19, one of the pulleys 21, of which is driven. A vertical endless conveyor 22 driven in an opposite direction to the endless conveyor 19 co-acts with said conveyor 19 to force the stalks downwards to the crushing and scraping means. Said means comprises two longitudinally corrugated crusher rolls 34 and 35 extending parallel with the scrapers 25 and 26 and rotated by means of belts connecting said rolls and the respective scrapers. A rigid crusher member 30 extends from a point just below the lower end of the conveyor 22 to a point below the lower scraper 26, said member being curved to extend around the corresponding sides of the scrapers and crushing elements. The lower scraper 26 is driven at a much greater speed than the upper one, as is also a beater 37, situated below the lower scraper. Separation of heavy core particles is brought about by radial blades 38 of said beater and they drop downwardly whilst the stalks are transferred to the ground by a loader wheel 39, an endless conveyor 41 and an opening 42 in the side of the box 1. A modified construction of the rigid member 30, Fig. 4 (not shown), consists of said member being in two parts, one part extending around one side of the upper scraper whilst the other part extends around the other side of the lower scraper. Means for reversing the rotation of the topmost scraper is shown in Fig. 5, wherein a collar 46 keyed to the scraper shaft 27 has oppositely extending lugs 50 which fit into opposed slots 49 in opposed bevel gears 47, 48, said collar being movable along said shaft, to enable a lug to engage with its complementary slot. The gears 47, 48 are driven by a gear 51 connected to a motor 52. Movement of the collar is by an arm 53 pivoted intermediate its length, and at one end entering a recess 54 in said collar and at its other end connected to a plunger 55 of a solenoid 56. Suitable means may be provided to vary the distance between the ends of the conveyors 19 and 22.

Title: Improvements in or relating to the construction of tunnels
IPC: E02D29/073
Filed: 1958-01-28
Abstract: 865,567. Tunnels. BERTLIN, D. P. Feb. 13, 1959 [Jan. 28, 1958], No. 2843/58. Class 85. A tunnel is built on a sea or river bed from a multiplicity of interfitting lengths 2, each length initially having a removable bulkhead 31, 32 near each end, by sinking a second tunnel length and guiding it so that one end thereof mates with the end of a first tunnel length already on the sea bed and from which water has been removed up to bulkhead 31 near the end to be mated; sealing the tunnel lengths together; opening the bulkhead 31 in the first tunnel length manually from within the said length so as to remove water from the neighbourhood of the joint between the lengths; and then removing water from the second tunnel length by removing or opening the second bulkhead 32. The lengths 2 are handled by means on mobile platforms 4 and supporting legs 5 of the kind used for off-shore oil-well drilling, and are provided, at one end, with feet 10 which rest upon platforms 7 which are formed by depositing screed from a retractible and revoluble pipe having a blade at the lower end to form the level surface. The ends 9 of the length are socketed and the other ends are spigotted and each length is guided during lowering to the length last laid by connecting links 24 which are formed to embrace and slide down the cables 13 of the last laid length, so that, finally, because the stub axles 21 are much below the axis of the descending length, the links 24 pivot about the axles 14 and swing the spigot into the socket. The tunnel length is first floated to the platform 4, the cables 13 are placed in recesses in the faces of the links and retained therein by complementarily recessed cover plates which are bolted to the links, the length is flooded sufficiently to sink it, and the mating ends are joined. A packing 29 is compressed as the external pressure forces the last laid length into the previous one, and the joint is finished with lead caulking 35. Settlement in the tunnel may be countered when it occurs by injecting cement grout 36 through radial channels 37. The stub axles 14, 21 are on metal plates secured to the lengths by bolts with internal nuts, and when the length is laid, the plates and stub axles may be released by removing the nuts. The bulkheads are built-in sections 11 secured to a frame 12 extending across the tunnel section, and include a pressure gauge 33 and a valve 34 for releasing water from a length being laid, to the main length of the tunnel. The laid tunnel is flanked by banks of rubble and is covered by sand retained between the rubble banks. The tunnel is divided by a horizontal floor, the upper section being for road traffic and the lower for rail traffic. A ventilation shaft 42 has pipes 43 projecting upwardly' to above the sand covering, foul air being forced out of these pipes. A casing 44 guides a shut-off plate and also a slide carrying two non-return valves, which are used in alternation, to permit repair of either valve. A warning beacon is positioned where the tunnel emerges from the water.

Patent GB-616285-A (GB)
Title: Method for producing non-siccative oils or crystallized hydrocarbons from rosin or rosin oil
Filed: 1946-01-30
Abstract: Hydrocarbon non-siccative oils or crystallized hydrocarbons are produced from wood rosin (colophony) or from oils obtained by the dry distillation of colophony, by heating with an amount of sulphur of the order of 1 per cent of the weight of the rosin or rosin oil, in the presence of ferric oxide and air or oxygen.  The sulphur is regenerated in situ by the simultaneous action of the oxygen and of the ferric oxide, which permits the reduction of the proportion of sulphur used from the 50 per cent or so formerly used.  No substantial evolution of sulphuretted hydrogen should occur.  The reaction may be carried out at approximately 250 DEG  C., the volume of air introduced into the mixture being controlled to obtain more or less complete regeneration of the sulphur.  In an example, 100 kg. of colophony, 1 kg. of sulphur and 3 to 5 kg. of ferric oxide are mixed and heated to 250 DEG  C., while air is injected into the mass for 6 hours at the rate of 8 cubic meters per hour.  The resultant oil is distilled and then does not dry when heated in an oven at 100 DEG  C. for 15 hours.  The oils produced in this manner are said to be suitable for use as lubricants, while the crystallized masses obtained by the treatment of rosin oil in a similar manner are said to contain high proportions of retene.ALSO:Hydrocarbon non-siccative oils or mixtures of crystallized hydrocarbons rich in retene are produced from colophony or from rosin oil by heating with an amount of sulphur of the order of one per cent of the weight of the rosin or rosin oil in the presence of ferric oxide and air or oxygen.  The reaction may be carried out at about 250 DEG  C., the volume of air introduced into the mixture being controlled to obtain more or less complete regeneration of the sulphur.  In an example, 100 kg. of colophony, 1 kg. of sulphur and 3 to 5 kg. of ferric oxide are mixed and heated to 250 DEG  C. while air is injected into the mass for 6 hours at the rate of 8 cu. metres per hour.  The resultant oil is distilled.  When rosin oil is similarly treated, crystallized masses such as retene are obtained.  The Specification as open to inspection under Sect. 91 refers also to the production of liquid hydrocarbons of the octohydroretene type.  This subject-matter does not appear in the Specification as accepted.
